What's new

It's fire play at Pokhran! Stunners from Iorn Fist FDR

Again wrong... neither did the RD93 meet the dimension/performance parameters set for Kaveri... neither did the Russian make any such offers.

They had offered it since years (last during MMRCA), you can simply google it and the performance parameters are pretty much what the original Kaveri K9 should have been, around 50kN dry, around 83kN wet, around 1t weight!
The lenght is not an issue, which should be obvious by the simple fact that the GE 404 (LCA MK1) / 414 (LCA MK2) and the proposed EJ200 are also clearly bigger than Kaveri as well, with a lenght of around 4m. Or that the MK2 don't need lenght changes of the airframe to fit the new engine, only fuselage and air intake modifications. The extra lenghtening of the airframe comes only by the addition of new fuel tanks.

How is length and diameter not an issue ?-- It requires a complete redesign[only fuselage and intake modification is not fun]-- Kaveri currently offers more at 52kN dry and 80-85kN wet-- K9 was supposed to be at 52kN dry and 90-95kN wet with improved service life- than what RD-93/33 offers-

Pokhran (Rajasthan): Frontline fighter jets, helicopters and transport aircraft of Indian Air Force on Friday displayed their operational and precision fire power capabilities during the force's first day-night exercise in a range in Thar desert in Rajasthan.

The military exercise event was titled as Iron Fist 2013.

Watched by President Pranab Mukherjee and Prime Minister Manmohan Singh, the exercise, one of the biggest conducted by the force, saw air–to-ground weapons firing and precision bombing by IAF aircraft at the range near Jaisalmer.

"This is the demonstration of man, machine, weapons and technology interfaces before the supreme commander of the armed forces", who is the President, IAF chief Air Chief Marshal N.A.K. Browne said.

Exhibiting their tremendous control over the flying machines, the pilots demonstrated their skills in manoeuvring a range of frontline planes like SU-30 MKI, Mirage 2000, Jaguar, MIG-21, MIG-27, MIG-29 besides Hawk trainers.

A highlight of the display was aerobatics and target bombing by indigenous Light Combat Aircraft (LCA) and flying by Light Combat Helicopters (LCH). Besides, the fire power demonstration IAF's helicopter team Sarang gave a thrilling aerobatics demonstration.

The Air Force also showcased its surface-to-air missile systems. The show was also witnessed by Defence Minister A.K. Antony, Rajasthan Governor Margaret Alva, Chief Minister Ashok Gehlot and defence attaches of friendly countries at the sprawling Pokhran Range.

The exercise highlighted IAF's capabilities to operate in a network-centric environment round-the-clock, the lethality and precision of its ground-based weapon systems and the efficiency of its special forces. Giving an insight into the exercise and the level of modernisation in the force, Air Chief Marshal Browne said IAF has progressed to execute seamless network-centric operations.

"By integrating our new inductions like the Su-30 MKI, C-130J, Mi-17 V5 helicopters and force enablers like AWACS and air refuellers into our overall operational matrix, we have ensured that the precious operational assets entrusted under our care are employed in the most effective manner. With the total integration of our sensors under the IACCS network, we have progressed closer to our goal of executing seamless network-centric operations," Browne said.

He said that IAF is fully geared to simultaneously conduct operations with sister Services- Army and Navy- at the tactical, operational and strategic levels.

"Also, continuing with our time honoured traditions, we remain ever committed to the important nation building tasks – be it while providing prompt relief to our distressed countrymen during natural calamities or while supporting our para-military forces deployed on various internal security assignments," he added.

The Air Chief said IAF has for the first time permitted a few young Flying Officers to take part in the demonstration on the HAWK trainers. "It is a fitting tribute to the confidence that the Air Force places in its future generations of young men and women as they perform in front of their Supreme Commander," he said.

After the opening remarks by Browne, the firepower exercise commenced with flag trooping by Mi8 helicopters and 'journey of IAF and indigenous package flypast', followed by another packages including one of 'net enabled operations'.

The opening of the thrilling grand exercise with helicopter fly past was followed by sorties by vintage aircraft Tiger Moth, the first basic trainer aircraft of the IAF.

As the show moved on, Swiss trainer aircraft 'Pilatus PC-7', the latest procurement by the IAF, displayed manoeuvres. A sonic boom generated by Mig-27 rocked the area which was followed by mixed flying by fighters and then helicopters. Fighter aircrafts performed fire power demonstration and destroyed mock targets on the ground.

Two types of bomb – iron bombs and laser guided bombs - were fired in the exercise. Targets which were successfully destroyed by the pilots were mock radar sites, tanks marshalling yards, terrorist camps, runway, BMP, communication hub and convoys among others.

Three SU-30 formed Trishul formation leaving people at the ground platform awestruck. The first prototype of LCH performed breathtaking manoeuvres such as moving back in the sky which are not possible in conventional helicopters. In addition, troop inspection of Garuds (IAF's special force) and NSG to neutralise a mock terrorist camp and display by para jumping team ‘Akash Ganga’ were demonstrated in the event.

In the daring feat, the IAF displayed more than 30 types of platforms and weapons systems amounting to a participation of over 200 aircraft.

Air Defence Operations, Counter Surface Force Operations, Urban Warfare and Combat Search Rescue Operations were among various aspects of fire power the force displayed in the event in which 'Air Warrior Drill Team' and 'Air Warrior Symphony Orchestra' also performed.

How is length and diameter not an issue ?-- It requires a complete redesign[only fuselage and intake modification is not fun]-- Kaveri currently offers more at 52kN dry and 80-85kN wet-- K9 was supposed to be at 52kN dry and 90-95kN wet with improved service life- than what RD-93/33 offers-

You really need to read up some things first before claiming things. Lenght as already explained, there is more than enough space to fit any of the light class engines into LCA, that's why nearlly all available version were considered. The only air intake modifications are only in the inlet and because the new engine need a higher airflow, while the fuselage modifications are required do to new parts for the engine, to be used on a single engine fighter. All this has nothing to do with the general lenght or diameter of the engine and neither would it have been an issue with the RD93, but we rejected Russian offers as stated.

As recent reports confirmed, K9 currently offers only around 49kN dry and around 71kN wet, the original specs were:
Maximum dry thrust : 52 kN
After burner maximum power thrust : 81 kN

The weight and drag increase of LCA resulted in the need of a new engine with at around 90kN wet, but that has never been a requirement for the K9, nor could it be achieved without help and a new core, which btw is what the RD33MK offers today in our Mig 29Ks and what is offered from Russia for JF17 with a possible RD93 upgrade.

RD-33/93.... 4229mm long... 1000mm diameter..... 1055kg weight.... 7.9 T/W ratio.
Kaveri........ 3490mm long.... 910mm diameter...... 1100kg weight.... 7.8 T/W ratio.
F-404........ 3912mm long.... 889mm diameter...... 1036kg weight.... 7.8 T/W ratio.
F-414........ 3912mm long.... 889mm diameter...... 1110kg weight.... 9 T/W ratio.
EJ-200....... 4000mm long.... 737mm diameter...... 989kg weight...... 9.2 T/W ratio.

IAF wanted Tejas modified to accommodate a more powerful engine which is heavier than the current engine hence only intake modifications and some design changes to meet other requirements... a larger or smaller engine automatically means a redesign of air frame and fuselage.... Su35BM fuesalage was totally modified from Su30K just because the diameter of engine was 27mm more and you talking about taking a jump of 100mm without any major modification or say only inlet modification.

Kaveri K9 specs.... on the website show what DRDO could come up with not what IAF wanted... If that was the case then F-404 is sufficient and no change was required.

The core in K9 is sufficient of producing 90kN with modifications to blades and some increase in diameter... It has shown potential and figure of about 85-86kN have been achieved in ground testing... sometime back.

The core in RD-93 is poorer evident of the fact that it has larger fan blades in spite of that it produces lower thrust as compared to other engines in similar class.. Increase the diameter of Kaveri to 1000mm and It would produce more than what RD-93 offers but that changes the geometry of the plane completely and extra spaces would be required to accommodate the larger engine.. and also a larger fuel tank as the engine becomes fuel hungry as It is working overtime to run larger blades and compressors also decreasing MTBO... and It is no longer LCA tejas but becomes MCA tejas.

sorry mate as per drdo offial statement dry thrust is 49 and wet 71 kn drdo is happy with dry but not with the wet thrust hence required foriegn partner for reducing weigth and after burning etc
